Banana Pi Expand Module Serial
：
Infinity cascade IO expand module
：
This module is designed specifically for the Banana Pi IO expansion modules. The
module expand 32 IO, Multiple modules can cascade, infinity cascade
，
infinity GPIO.
I2C GPIO expand module
：
This module is designed specifically for the Banana Pi IO expansion modules. The
Module use I2C bus to connect to Banana Pi. The module expand 8 Bidirectional
GPIO and wit isolation protection function which can effectively excessive external
voltage. There are 8 I2C address, you can choose one of them through setup the
jumper. Multiple modules can cascade and maximum cascade 8 modules!
Prototype development module
：
The Prototype development module is designed specifically for the Banana Pi. The
module suitable enthusiasts and user can weld peripheral to the module
；
The
module expand some amphenol connector and some SMT, so the user can finish
prototype test easily.
Berryclip expand module
：
The BerryClip module is designed specifically for learning how to use the GPIO of
Banana Pi. There are 6 multiple color LED, 1 button and 1 Buzzer on the module.
Berryclip(DIY) expand module
：
The module is not the end product, you need weld them by yourself. The function of
the module is the same as BerryClip module.
UNO compatibility module
：
The module makes Banana Pi compatible with Arduino Uno and many Arduino
Shields. The module’s GPIO is the same as Arduino Uno and you can choose the
voltage of GPIO between 5V or 3V through setup jumper.
T Electric level convert module
：
The module expand the GPIO of Banana Pi to breadboard. It convert 3.3V electric to
5V electric level, then the Banana Pi can connect many 5V electric level peripheral.
IO extraction module
：
The module expand all of GPIO of Banana Pi to breadboard.
